In 1989, I purchased one of the first graphing calculators on the market - a Casio FX-7000GA for my math class. It used three CR2032 batteries, so when it died, you couldn’t use it for weeks until you could find new batteries. I even programmed it to factor numbers and calculate pi!

Although I have many years of formal education, most of what I've learned has come from experimenting and trying to solve problems on my own. Once an idea for a project is set in my mind, it is all-consuming and one must learn everything possible about the subject on the way to the outcome. For learning is more than reading books and spoken word, it is hours of frustration, trial and error, and one sudden flash of insight when the world magically makes sense. It is during this moment when I am truely alive.
